This worked for me on OSX     allow variable to opened as files from io import StringIO    library to map other strange  accented  characters back into UTF-8 from unidecode import unidecode    cleanse input file with Windows formating to plain UTF-8 string with open filename   rb   as fID      uncleansedBytes   fID read         decode the file using the correct encoding scheme        probably this old windows one       uncleansedText   uncleansedBytes decode  Windows-1252          replace carriage-returns with new-lines     cleansedText   uncleansedText replace   r     n          map any other non UTF-8 characters into UTF-8     asciiText   unidecode cleansedText     read each line of the csv file and store as an array of dicts     use first line as field names for each dict   reader   csv DictReader StringIO cleansedText   for line entry in reader        do something with your read data

I know this has been answered for quite some time but not solve my problem  I am using DictReader and StringIO for my csv reading due to some other complications  I was able to solve problem more simply by replacing delimiters explicitly   with urllib request urlopen q  as response      raw data   response read       encoding   response info   get content charset  utf8        data   raw data decode encoding      if   r n  not in data            proably a windows delimited thing   try to update it         data   data replace   r     r n     Might not be reasonable for enormous CSV files  but worked well for my use case

It ll be good to see the csv file itself  but this might work for you  give it a try  replace   file read   csv reader self file    with   file read   csv reader self file  dialect csv excel tab    Or  open a file with universal newline mode and pass it to csv reader  like   reader   csv reader open self file   rU    dialect csv excel tab    Or  use splitlines    like this   def read file self       with open self file   r   as f          data    row for row in csv reader f read   splitlines         return data

If this happens to you on mac  as it did to me     Save the file as CSV  MS-DOS Comma-Separated  Run the following script  with open csv filename   rU   as csvfile      csvreader   csv reader csvfile      for row in csvreader          print      join row

For Mac OS X  save your CSV file in  Windows Comma Separated   csv   format

I realize this is an old post  but I ran into the same problem and don t see the correct answer so I will give it a try  Python Error    csv Error  new-line character seen in unquoted field   Caused by trying to read Macintosh  pre OS X formatted  CSV files  These are text files that use CR for end of line  If using MS Office make sure you select either plain CSV format or CSV  MS-DOS   Do not use CSV  Macintosh  as save-as type    My preferred EOL version would be LF  Unix Linux Apple   but I don t think MS Office provides the option to save in this format
